Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Tue Apr 26 17:05:56 GMT 1994 Year: 94 Doy: 116 Observer: yasukawa COMMENT: Tue Apr 26 17:06:07 GMT 1994 Cool, clear, light southeast wind. Temp = 48 degrees F. Tue Apr 26 17:08:22 GMT 1994: Patrol Start MKIII COMMENT: Tue Apr 26 17:14:28 GMT 1994 Opening shutter, changed mind about doing dark trace now, but forgot to take shutter out until partway into first coronal scan. Tue Apr 26 18:00:21 GMT 1994: Filemark-Calibration COMMENT: Tue Apr 26 18:14:17 GMT 1994 Hydraulic ladder control had a broken wire in it, causing the ladder to extend if control was jostled, creating a potential hazardous situation if working close to the spar or dome. Repaired it. Tue Apr 26 19:00:17 GMT 1994: Filemark-Calibration COMMENT: Tue Apr 26 19:45:55 GMT 1994 Opening top of dome shutter. Stopping DPMON, MKIII continues. Tue Apr 26 19:47:01 GMT 1994: Patrol End Tue Apr 26 19:52:22 GMT 1994: Patrol Start Tue Apr 26 20:02:17 GMT 1994: Filemark-Calibration COMMENT: Tue Apr 26 20:08:54 GMT 1994 $$$ Orographic clouds starting to congregate around site. COMMENT: Tue Apr 26 20:14:53 GMT 1994 Finally found some time to take a look at the GONG drive mechanism that failed a long time back. This was the unit they sent out to replace the one that is running now that had a loose shaft/clutch. There is extensive corrosion on the internal wiring due to water that leaked inside. Uncertain if a repair is worthwhile at this time. COMMENT: Tue Apr 26 20:17:59 GMT 1994 $$$ in orographic clouds. MKIII COMMENT: Tue Apr 26 20:19:57 GMT 1994 I just noticed that the Exabyte tape is popped out. Checking to see if Scan-log changes, i.e it still thinks it is writing files, otherwise last complete file was written at 20:15:50. Tue Apr 26 20:22:09 GMT 1994: Patrol End MKIII COMMENT: Tue Apr 26 20:26:09 GMT 1994 Cleaning attempt failed, tape ejected when loaded. Cycled Exabyte drive power, loaded cleaning tape. Head cleaning successful. Loaded tape that had popped out to see if I can rewind it. MKIII COMMENT: Tue Apr 26 20:57:20 GMT 1994 Tape wouldn"t load. Powered down and removed manually. Tape was a bit bent out of shape ***** WATCH IT, FOLKS ! ***** H00750 ***** Reassembled unit and loaded another tape. Load was successful. Unload was successful. Must have been a bad tape. I hope Boulder can retrieve the data on it. DO NOT RECYCLE THIS ONE! COMMENT: Tue Apr 26 21:01:59 GMT 1994 Activity report: QP: 247; 265; 297; No coronal activity TAPES: MKIII: H00750 -- Possibly a bad cartridge, No double EOF at end of data, May not have EOF at end of last file (20:15). DPMON: P00052 LOW-L: L00031 in unit 0 running.
